Salut à tous
Ben bien du courage pour allez plus loin
Il faudrait un aperçu plus précis du thalle mais même avec cela semble super ardu
je cite lastragon :
C. chlorophaea, sensu stricto, which according to various workers is less restricted to acidic habitats and is widespread in Britain, C-, K-, KC-, Pd+ red, medulla not fluorescent under UV light. The photographed material has distinctly denticulate cup margins.
C. grayi, said to be scarcer and more strictly confined to acidic habitats, C-, K-, KC-, Pd+ red, medulla fluorescing bright blue under UV light (not to be confused with reflection of visible blue and violet light off the lichen surface). Material shown here appears to be a reasonable match to the description and photograph of Norwegian material provided by Holien et al., Gunneria, 51: 7-26 (1985), including presence of podetial squamules. The cup margins are distinctly pinkish. It should be noted that the name 'C. grayi' has commonly been used in a broader context, covering C. merochlorophaea and other taxa.
et C fimbriata pourquoi pas ?
Les Cladonia c'est bô mais c'est tout ...
